WILLIAM THUM AND HUGO TIIUM, OF GRAND RAPIDS, MICHIGAN.

STICKY FLY-PAPER.

SPECIFICATION forming part of Letters Patent No. 612,686, dated October18, 1898.

Application filed April 5, 1898. Serial No- 676,563. (No model.)

To aZZ whom it may concern:

Be it known that we, WILLIAM THUM and HUGO THUM, citizens of the UnitedStates, residing at Grand Rapids, in the county of Kent and State ofMichigan, have invented new and useful Improvements in Sticky Fly-Paper, of which the following is aspecification.

This invention relates to certain. new and useful improvements in stickyfly-paper, and relates particularly to fly-paper put up in rolls havingthe sticky material applied to both sides of the strip of paper or webforming the roll; and the objects of our invention are, first, toprovide, in a suitable form for hanging a strip of paper or web, asuitable core upon which the web is rolled and to which adrip-receptacle may be readily attached, and, second, to combine withthe core a web rolled thereon and a receptacle so attached as to preventthe web from unwinding too freely-from the core, thereby enabling theuser to unwind only such portions of the web as are used at any onetime. These objects we accomplish by means of the mechanism illustratedin the accompanying drawings, in which Figure 1 shows an elevation ofthe roll partially unwound with the drip-receptacle detachably securedto the core. Fig. 2 shows an end view of the same. Fig. 3 shows amodified form of the core and the attachments of the drip-receptacle tothe core.

Similar letters refer to similar parts throughout the several views.

A represents the web, which is supplied with the sticky inaterialandwhich is adapted to be wound upon the core D.

D represents the core, which in the example of our invention shown inFigs. 1. and 2 has a conical or other projection at either end adaptedto engage with the ears of the dripreceptacle.

B represents the drip-receptacle,which may i be constructed in anysuitable form and provided with ears or projections C O, which engagewith the core. In the example of our invention shown in Figs. 1 and 2these ears 0 O are adapted to fit over the conical pro jecting ends ofthe core, while in the example of our invention shown in Fig. 3 the earsproject inwardly into cavities in the ends of the core. We prefer toconstruct the receptacle of metal or other material which will give aspring-pressure between the ears and the core for the purpose ofincreasing the friction between the core and the receptacle. Thisfriction between the core and the receptacle may be increased by anysuitable means. The object of the frictionis to prevent the web fromunrolling by the weight of the receptacle and core and to retain thelength of web unrolled mechanically at any required point. By thisconstruction also the roll may be completed and the receptacle appliedby merely crowding it over the core, so that the ears of the receptaclewill engage with the projections or depressions in the core, as the casemay be. The free end of the web is preferably provided with an openingor hole adapted for use in hanging the web and rollin suitable positionfor use. A strengthening-piece E may be applied to prevent the web fromtearing out.

Having thus described our invention, what we claim to have invented, anddesire to secure by Letters Patent, is-

1. A strip of sticky fly-paper forming a web, a core upon which said webis wound,a drip-receptacle having spring core-retaining devices at itsends which detachably engage the ends of the said core, substantially asdescribed.

2. Astrip of sticky fly-paper forming a web, a core upon which saidwebis wound, a dripreceptacle detachabl'y connected to the said core, andadapted to press thereon so as to produce sufficient friction to preventsaid web from unwinding by the weight of the core and receptacle,substantially as described.

Astrip of sticky fly-paper forming a web, a core upon which said web iswound,a clamp adapted to press upon the core so as to produce sufficient friction to prevent the said web from unwinding by the weightof the core and clamp.

In testimony whereof we have hereunto set our hands in presence of twosubscribin g witnesses.
